Abstract: The technologies described herein are generally directed toward retrieving data from streaming storage. In an embodiment, a method can include receiving an application data request that identifies application data to be retrieved from a sequence of stored data chunks that correspond to a stored stream of data. The method can further include, based on the application data request, estimating a first estimated location of the application data, with the first estimated location including an identified chunk of a sequence of chunks. Further, the method can include, based on the application data request and a characteristic of the identified chunk, retrieving, by the system, a first data block that is estimated to comprise the application data, resulting in a first retrieved data block.

Abstract: The present disclosure relates to an information sending method, apparatus, system and a computer readable storage medium, and pertains to the technical field of computers. The method in the present disclosure includes: analyzing video data of an offline user to determine an attribute of the offline user; searching for historical access information of at least one online user matching the attribute of the offline user; and determining at least one object recommended to the offline user according to the historical access information of each of the at least one online user, and sending information of the at least one object to the offline user.

Abstract: This disclosure relates to sensors comprising an elastomeric body incorporating a plurality of discrete electrical conductors such that an electrically conductive path can be formed within the elastomeric body via conduction between neighbouring conductors, and the elastomeric body includes at least one slit passing between neighbouring conductors. These sensors may be included in circuit structures, decals and vibration sensors. Also disclosed are methods of preparing the sensors, circuit structures and decals, and methods of using the sensors, circuit structures and decals.

Abstract: Disclosed is a blade replacement apparatus of an electric instrument, which is used to replace blades connected by a bolt, the bolt extending along a first axis, the blade replacement apparatus comprising a nut that fits the bolt to fix the blade, a nut loosening/tightening member, a locking member, and an operating member, one of the nut loosening/tightening member and the operating member having a first matching portion, the locking member having a second matching portion, wherein the operating member is movable between an operating position and a non-operating position, the operating member allowing a user to perform an operation by hand without using any instruments; when the operating member is in the non-operating position, the first matching portion engages with the second matching portion, and the rotation of the nut loosening/tightening member around the first axis is obstructed by the locking member; when the operating member is in the operating position, the first matching portion is disengaged fro

Abstract: A commodity recommendation method, apparatus and system, and a computer readable storage medium. The method includes: analyzing an image of a specific offline customer currently entering a store to obtain an attribute of the specific offline customer; determining an online user matching the specific offline customer according to the attribute of the specific offline customer; constructing a collection of popular commodities of the store according to commodities corresponding to stay positions of offline customers who have entered the store before; and recommending a commodity to the specific offline customer according to a historical shopping information of the online user and the collection of popular commodities.
